The Wisconsin DNR recently created a short video on Heterobasidion root disease (HRD) to compliment the updated guidelines that were released in 2019. The 5-minute educational video covers HRD biology, its significance as a tree disease, signs and symptoms, as well as preventative measures that landowners can take to reduce its introduction and spread. This is a great video for forestry professionals, landowners and the general public to learn more about HRD.

If you would like more information about HRD or to find the link to the video on YouTube, visit the DNR HRD webpage. There are numerous resources located on the right-hand side of the page, including a downloadable version of the guidelines, two maps of known HRD locations, and a two-page factsheet. You can also contact your local forest health specialist for more information.
